If you exceed the maximum set by the memory clock, you’ll get corruption on the screen during graphics operations, as you will be starving the HW BitBlt engine of clock cycles. So for unexplained problems not addressed above, please try to alter the clock you are using slightly, say in steps of 0. It has the same ID and is identified as a when probed. Legal values for this key are depth dependent. However luckily there are many different clock register setting that can give the same or very similar clocks. This will prevent the use of a mode that is a different size than the panel. Similar to the but has yet higher maximum memory and pixel clocks.

The chipset has independent display channels, that can be configured to support independent refresh rates on the flat panel and on the CRT. It is possible to turn the linear addressing off with this technollogies.

The first two are usually loaded with In this case the driver divides the video processors dotclock limitation by the number of bytes per pixel, so that the limitations for the various colour depths are. This driver must be considered work in progress, and those users wanting stability are encouraged to use the older XFree86 3. So the driver will attempt to round-up the virtual X dimension to a multiple technoloties 64, but leave the virtual resolution untouched.

Using this option the user can override the maximum dot-clock and specify any value they prefer. As use of the HiQV chipsets multimedia engine was supposed to be for things like zoomed video overlays, its use was supposed techhologies be occasional and so most machines have their memory clock tecbnologies to a value that is too high for use with the ” Overlay ” option.


Note that for the this is required as the base address can’t be correctly probed. This sets the physical memory base address of the linear framebuffer. However it additionally has the ability for mixed 5V and 3. On a cold-booted system this might be the appropriate value to use at the text console see the ” TextClockFreq 665555 optionas many flat panels will need a dot clock different than the default to synchronise.

Alternatively the user can use the ” TextClockFreq ” option described above to select a different clock for the tecnologies console. Firstly, the ct chipset must be installed on a PCI bus. Try deleting theses options from xorg. This support can be used to give a single display image on two screen with different refresh rates, or entirely different images on the two displays.

If you have a problem with the acceleration and these options will allow you to isolation the problem. If this option is removed form xorg.

The server will limit the maximum dotclock to a value as specified by the manufacturer. The lower half of the screen is not accessible. The current programmable clock will be given as the last clock in the list. Tefhnologies is the reason tehnologies the drop in the dot clock.

Option “NoAccel” This option will disable the use of any accelerated functions. This allows the user to select a different clock for the server to use when returning to the text console. However the panel size will still be probed.


It might affect some other SVR4 operating systems as well. Although the authors of this software have tried to prevent this, they disclaim all responsibility for any damage caused by the software. Most of the Chips and Technologies chipsets are supported by this driver to some degree.

For chipsets that support hardware cursors, this option enforces their use, even for cases that are known to cause problems on some machines.

For the chips either using the WinGine or basic architectures, the chips generates a number of fixed clocks internally.

This can be found from the log file of a working single-head installation. Note that this option using the multimedia engine to its limit, and some manufacturers have set a default memory clock that will cause pixel errors with this option.

Leaving too little memory available for the cache will only have a detrimental effect on the graphics performance. Also the maximum size of the desktop with this option is x, as this is the largest window that the HiQV multimedia engine can display.

Which results in tecnologies x mode only expanded to x
